as other said, u NEED to connect ur monitor with ur GPU. Go get a VGA convertor. Ryzen does not have iGPU, so connect monitor to mobo is a big nono.
 
As for the RAM, go into BIOS after u connect monitor to GPU and get it post. it will show at what freq is the RAM working at. The least it should be working on is 2667Hz. anything higher is not guaranteed.

It will set your memory speed to 2133 as stock after first boot.
You can overclock it as far as the mobo/IMC will allow it.

Yeah it will work.
2666 is max official JEDEC speed.
You can OC as far as the BIOS numbers go.

The thing is the r5 1600 doesnt have integrated graphics, your gonna need the gpu to get any video, so you need to connect via hdmi or dvi (or any ports that your gpu and monitor share).

Ryzen has no integrated graphics.
You need a connection from your GPU to your monitor.

Dont worry, i have the same cpu/gpu combo and it works great! Enjoy your new build

THe Dell seems like the only IPS monitor out of the 4. I would recommend you get that one, It's worth it.

My brother uses the InWin 301 and for $70 USD on newegg, its a tempered glass case and he really loves it, and its not too much of a challenge to build in. 

With nine minutes to spare!

I'm starting a timer

you may have to send it to the US

I think just after reading the reviews it should be clear...
 
And yes, ram manufacturers matter... 
 
In my own experience ADATA is an excellent ram manufacturer, never had any issues with ADATA ram for over 20 years. The only thing with ADATA, they just make "simple and sometimes stylish rams" without RGB. Which is ok for me, but some people need the bling, makes them feel the system is faster while it blings...
 
As for kingston for example, some rams are good, some cheaper on smaller pcbs are kind of whacky even in intel mobos. Even though they are not defect per se.

The quality itself is usually not very different between manufacturers, but the quality control and Support is better on some manufacturers.

As far as I know, Gigabyte AB350N-GAMING-WIFI ITX is the cheapest and most reliable motherboard that supports Ryzen.

You are already asking too much as I have built the computer in June and I am going to travel with it for the first time on the 22nd September.
I have read a lot of stories about travelling with the Node 202 and I can report what I read on the web to answer your first question:
It usually is not a problem. If they say anything you can just say that it is a console (they do look like a console), and you are a techie guy.
 
And for the second question I don't think it will be a problem as I have already travelled with: 2 laptops, 1 PS4, 1 Nintendo 3DS in the same backpack, and they
didn't say anything to me.
 
EDIT: If you leave me a PM, I will tell you how it goes on the 22nd.

I move between UK and Italy with the plane several times a year. Because of this I settled with the Node 202.
I will be honest, CPU cooling is great even with the low-profile Cryorig C7 (no OC), but cooling the RX 580 was difficult (that is probably also because of it's high wattage). I have just bought a fan to put below the GPU which should drop temps by 10C* according to YouTube reviews, so it will be alright as the GPU will run at 60-70C* (overclocked considering the RX 580 is an OC'd 480).
 
In my opinion, go for the slim case if you have to fly with it. No chance your computer will survive a flight in the hold, you have to keep it as a carry-on, and a slim case is perfect for that.

I would stick with 3200Mhz (3000 at least)
